Compounds having the structural formula:
are disclosed wherein
there are 0-4 R groups and
R is e.g. hydrogen, lower alkyl, halo-loweralkyl, hydroxy, lower alkoxy, halo, lower alkylthio or lower alkylsulfinyl;
R1 is e.g. hydrogen or lower alkyl;
Z is (a) -(CH2)o-n, n being 0-10;
(b) -CO(CH2)1-n-;
(c) -(CH2)1-n-CO-; or
(d)
R2 is e.g. hydrogen or lower alkyl;
R3 is hydrogen, lower alkyl, hydroxy, loveralkoxy or halo; and
X-Y is e.g. -O-CH2- or -S-CH2-.
Those compounds have been prepared via hydrolysis of a precursor or decarboxylation of a precursor-diacid. These tricyclic compounds are found to have high analgesic and anti-inflammatory activities but low ulcerogenic side effects.

Tricyclic derivatives of substituted pyrrole acids, e.g., substituted 4,10-dihydro-10-oxo-1H-[1]benzoxepino[4,3-b]pyrrole-2-acetic acids or the 5-thia analogs thereof have been prepared via hydrolysis of a precursor or decarboxylation of a precursor-diacid. These tricyclic compounds are found to have high analgesic and anti-inflammatory activities but low ulcerogenic side effects.
